I want to create a a sequence diagram which shows this signal being sent from one lifeline to another, so I have created a message between the two, double-clicked on it, changed the type to asynchronous | signal and using the dialogue box, navigated to the appropriate model element. Once done, EA will auto-populate the "Attributes" section of the message dialogue box with the name of the signal attribute (helpful!)

However, if I subsequently update the name of the attribute of the signal, the sequence diagram attribute does not automatically update (less helpful)

Does anyone know if there is a way to get EA to refresh the attribute names on a sequence diagram. I have already tried reloading it and that doesn't do the trick
